Default Re: face palm hp to cc help

Yeah, ratio of hp to cc is a very variable thing. Right now, That'sDax has a KTMC 2-stroke that is stated to put out 9 hp at 12,000 RPM. Nine horse from 49 cc. That would curl your hair a bit.
So many things about an engine influence horsepower, like backpressure, air-fuel mix, air temperature, size of carburettor venturi, octane rating, proper spark, and so on.
